The Sun will eventually end up as a what?
Earth's sun is currently a main sequence star which has a small mass. Eventually it will expand into Red Giant star once the core runs out of hydrogen and then helium gas. After the Red Giant phase, the star throws off its outer layers and then becomes a planetary nebula. A sun-like star will either become a white dwarf or black dwarf following the planetary nebula.
When a star has no fuel left and its outer layers escape into space what is its remaining core called?
When the layers escape into space, this is classified as a planetary nebula. What usually is left behind is a white dwarf.
What is the atomic process that occurs in the core of stars?
Nuclear Fusion occurs in the core of stars.
What is produced when a red giant explodes?
Depends on the mass of the star. A star the size of our Sun will eject its outer layers, forming a planetary nebula with the core of the star exposed, cooling to become a white dwarf. Larger mass stars will explode as a supernova, creating a shock wave of stellar matter, the core either condensing to a neutron star or a black hole.
How does a star turn into a white dwarf star?
A white dwarf is what stars like the Sun become after they have exhausted their nuclear fuel. Near the end of its nuclear burning stage, this type of star expels most of its outer material, creating a planetary nebula. Only the hot core of the star remains. This core becomes a very hot white dwarf, with a temperature exceeding 100,000 kelvin.
What happens during the life cycle of a star with two or three stellar masse?
A low mass star begins as the helium fuses into carbon and the core collapses. The outer layer of the star are expelled and form a new planetary nebula. The core remains as a white dwarf and cooled to become a black dwarf.
How a star becames a white dwarf?
A white dwarf is the core of a dead star. As the star runs out of fuel, it expands into a red giant, as the shell of the red giant became a planetary nebula, and the core shrinks and became a white dwarf.
How are giant stars and white dwarf related?
A giant star is a dying star that expanded, and the core shrinks are the same time. When the shell of the giant star drift into space as planetary nebula, the core became a white dwarf. The white dwarf is made from the core of the giant star.
How are planetary nebulas different from stars?
Stars are balls of gas that undergo nuclear fusion and have a core, their light come from the energy released during nuclear fusion. Planetary nebulae are the blown-off shells of dying red giant stars, the light of a planetary nebula come from ionized gas and light of other stars.

Can a planetary core be cold?
Certainly, a planetary core can be cold. The heat of our own planetary core is the result of radioactive decay of various elements in the core and mantle, but eventually that heat source will be used up, and the residual heat will gradually leak away into space. There could be other planets which never had much or any abundance radioactive content in the first place.

There is enough fuel remaining in the sun to last for another?
Roughly 5 billion years. It will expand into a red giant followed by throwing off its outer layers forming a planetary nebula. The only thing left over will be the extremely hot core that will cool into a white dwarf over billions of years.
Do gas giants have a solid core?
Probably yes, but planetary scientists are still not certain about it.
